  取代的7-氨基香豆素-3-羧酸酯衍生物的合成及荧光性质

  摘要：

  已经合成了各自含有马来酰亚胺的4-三氟甲基或6-溴取代的7-二乙基氨基香豆素-3-羧酰胺衍生物2和3，作为蛋白质中硫醇基的潜在荧光标记试剂，并且已经确定了它们的荧光性质。4-三氟甲基取代的化合物2的Stokes位移比缺少该基团的同类化合物要大得多，但是两种新的香豆素的荧光量子产率均很低（low f）。当存在4-三氟甲基取代基时，3-羧酰胺非常不稳定地水解。7-二乙基氨基香豆素-3-羧酸乙酯17的溴化分别得到6-和8-溴衍生物18和19，以及还有8-溴-7-一乙基化合物20.φ ˚F后者的化合物比其二乙氨基类似物19的化合物大100倍。荧光寿命测量结果支持基于扭曲的分子内电荷转移（TICT）模型的解释，以解释ϕ f的这些大差异。

• Evaluation of Synthesized Ester or Amide Coumarin Derivatives on Aromatase Inhibitory Activity

  Aromatase inhibitors are effective for the treatment of diseases such as breast cancer, which has led to an increase in their demand. However, only a limited number of aromatase inhibitor drugs are currently being marketed. In addition, considering the important aspect of drug resistance, the development of newer drug types is required. We have been developing inhibitors with backbone structures that differ from existing aromatase inhibitors. In this regard, we previously reported that diethylaminocoumarin dimers and thiazolyl coumarin derivatives possess strong aromatase inhibiting capabilities. In this study, we further examined the structure activity relationships of coumarin derivatives synthesized from thiazolyl coumarin derivatives and their aromatase inhibiting capabilities. Consequently, amide coumarin N-benzhydry1-7-(diethylamino)2-oxo-2H-chromene-3-carboxamide (IC50 values 4.5 mu M) is inhibitor of aromatase. This inhibitor was found to be comparable aromatase inhibitory activity to the 1st generation aromatase inhibitor aminoglutethimide (3.2 mu M). Substitution of the amide group on the amide coumarin derivative affects the aromatase inhibiting activity. Our findings suggest that the structure of each substituent changes the orientation of the compound in the active site of aromatase, thus creating a difference in their activities.

  boxamide derivatives 2 and 3, each containing a maleimide have been synthesized as potential fluorescent labeling reagents for thiol groups in proteins and their fluorescence properties have been determined. The 4-trifluoromethyl substituted compound 2 has a significantly greater Stokes shift than the comparable compound lacking this group, but both the new coumarins have low fluorescence quantum yields
